Pedders AHC Suspension Conversion Kit – Toyota LandCruiser 100 Series / Amazon (4.5 Petrol & 4.2 Diesel)
This Pedders kit is designed to replace the factory-fitted AHC (Automatic Height Control) suspension system used in the Toyota LandCruiser 100 Series. The AHC system relies on hydraulic fluid and pressure spheres to control vehicle height and ride comfort. While innovative, AHC systems often develop issues with age—repairs can be complex and expensive.
Pedders offers a cost-effective and reliable alternative: a complete conversion to conventional coil spring and torsion bar suspension. This solution is ideal for owners looking to eliminate AHC-related faults and restore predictable ride quality.
What's Included
Front torsion bars
Reinforcement plates for torsion bar mounts
Rear coil springs
Shock absorbers (front and rear)
Instructions on disabling the AHC system (to prevent dash warning lights)
Because AHC performance can vary depending on system condition, we offer several kit variants to suit different usage needs. Ride height and comfort may differ slightly depending on how your AHC is currently functioning.
Kit Variants
Kit 803202 – Standard Suspension Conversion Kit
Designed for vehicles that are typically unladen or tow light to moderate loads. This kit may raise the vehicle by up to 1 inch depending on the condition of your AHC system. Ride may be slightly firmer than the original AHC "comfort" setting, but most users report an overall improvement.
Kit 803203 – Suspension Conversion + Lift Kit
Includes raised rear springs for an average of approximately 2 inches of lift. Ideal for users wanting a slight height increase with standard load use.
Kit 803072 – Heavy Duty Load Carrying & Towing Kit
Ideal for vehicles that regularly carry heavy loads or tow trailers. This version includes heavy-duty rear shocks for improved load handling. Ride comfort when unladen will be firmer.
Kit 803093 – Heavy Duty + Lift Kit
Same as Kit 803072 but with raised rear springs, providing approximately 2 inches of lift for enhanced ground clearance when towing or loaded.
All kits are suitable for Toyota LandCruiser 100 Series (Amazon) with 4.5L petrol or 4.2L diesel engines. Vehicle height measurements are based on 16-inch wheels, but the kit will fit regardless of your current wheel size.
